Important Notes:

It is assumed that users have adequate soldering skills and troubleshooting skills to assemble the DSO138 kits. We don't guarantee that you can get a working deice in the end. But we make as much efforts as we can to help you approaching that goal.

Each main-board has been tested to ensure no short or open on MCU soldering. Each LCD board is also tested to verify soldering is good and display is functional. However, all the rest components are provided with good quality.
